Question
QUESTION: I have used the 4 step Turf Line fertilizing program for sometime.  I follow the program according the the directions. This fall grubs have eaten portions of my lawn and the animals seem to continue destroying my lawn even in the cold weather. I am looking for direction on how to deal with this in the spring.  Do I reseed my lawn and then put grub killer down in early spring or should I put grub killer down, wait a period of time and then seed my lawn.

ANSWER:  Effective grub control in Florida requires some work which you will find very interesting. The best resource is your County Extension Service but in a nutshell, here is what you need to do.
Identify the grub accurately. This is essential.
Decide on the best control product(s).
Apply at the most appropriate time. This will be a combination of what type of grub and what product you decide to use.
Ensure that all of the label requirements are met. You will be using products which are quite expensive so 'load the dice' in your favor to assure the best chances of success.
I could not find out the active ingredient in the "Turfline" product which you are using so I cannot comment as to why it has not been working for you.

QUESTION: Turf Line is produced here in Rochester, New York where I live.  But my question is do I reseed with fresh dirt in early spring and then put down grub killer when it is required.  I don't want to start new grass and then the chemicals from the grub killer kills the new grass.  We are getting some snow off and on and I continue to see spots where my grass is dieing and animals are ripping it up.  I take pride in my lawn and it is really looking bad.  I sent an e-mail to the company and they have not answered in 3 weeks.  Thanks for your help.

Answer
One of the reasons why I advised identifying the grubs accurately is because these insects move up and down in the soil, depending upon the stage of their development. In your area this habit may also be influenced by temperature. I am thinking that you might apply a product at a time when the grubs are deep in the ground, beyond the range of the chemical's effectiveness.
If you apply a chemical according to the label directions - rate, coverage, weather conditions, stage of growth of grass, stage of insect development etc., it is unlikely that you will cause damage to your turf.
